Spread rate check (determining the calibration factor)
AmaSpread+ BAG0126.4 09.17
8 Spread rate check (determining the calibration factor)
DANGER
Secure the tractor and implement against unintentional rolling
and unintentional lowering of the tractor three-point hydraulic
system.
The calibration factor for the spread material determines the regulat-
ing behaviour of the AMASPREAD+ and is dependent on
• the flow characteristics of the material to be spread.
• the entered spread rate.
• the entered working width.
• The flow characteristics of the spread material may change even
after a brief storage period.
• For this reason, determine the calibration factor for the spread
material before each use.
• Always redetermine the calibration factor for the spread material
ο if the spread rate has been changed.
ο if deviations occur between the theoretical and actual
spread rates.
Enter the calibration factor according to the setting chart in the Set-
tings menu before determining the precise calibration factor.
The determined calibration factor is adopted in the active settings.
The desired method for checking the spread rate can be set in the
Setup menu.
Slug pellets, fine seeds:
• Before operation, a simulated speed must be entered. To check
the spread rate, however, the speed must be 0.
• For the spread rate check, spread at least 10 kg of spreading
material.
• Offline calibration and online calibration with weighing technolo-
gy is not possible for slug pellets and fine seeds.
